MTH Shay Problem

[Dave Connolly]

 Sounds as though the wire from the pickup roller is shorted to ground if it's tripping a breaker. It may have got hot enough in the derailment to burn off some insulation.

Had a derailment and a slight amount of smoke from the Shay, now when I set it on the track, it trips the circuit breaker in the transformer, any ideas as to what might have happened? Thanks much, Jake
